BOTTLE-FORMING MACHINE.

Application filed .Tune 26, 1926. Serial No. 118,731.

The present invention relates to improvements in glass bottle formingmachines, and has for an object to provide a compact, circular machinefor accom} )lishing at various stages the blank and finished moldingoperations through the coordinated use of coacting mechanisms groupedfor easy and convenient control by few operatives.

It is another object of the inventionlo secure simplicity in theconstruction and operation of the machine, and a much higher speed inthe operation through such simplicity.

With the foregoing and other objects in view, the invention will be morefully described hereinafter, and will .be more particularly pointed outin the claims appended hereto.

Figure 17 is a section taken on the line 17-17 in Figure 14, and

Figure 18 is a section taken on the line 18-18 in Figure 2. t Referringmore particularly to the drawings and for the present to Figure 2, 20designates a track or supporting surface upon which the wheels 21carrying the machine are arranged to travel. These wheels are carried bya base 22 of hollow construction to which is bolted the air pipe 23.

The base 22 supports the hollow pedestal 24, which in turn supports forrotation the hollow arm structure or spider 25. This hollow armstructureor spider, is shown in Figures 3 and 4, and consists.in the hollow arms26 extending radially out from the central hollow ring 27 having theinturned circular flange`28 at its upper end.

- The ring 27 is provided with the openings 29 to register with thehollow arms., and at the outer ends the hollow arms are made withbearing openings 30 to receive and'support the transfer appara-tus, asshown in Figure 7. Further constructional features of the spider orhollow arm construction will be described later in connection with saidFigure 7. i

To return to Figure 2, the flange 28 of the spider construction isarranged to overlie a shoulder 31 at the upper portion of the hollowpedestal 24 and ball races are provided between these two parts for theanti-friction bearings 32.

The spider construction is rotated upon 33 the pedestal 24 by means of agear whee affixed beneath the spider and surrounding the hollow,pedestal, with which gear wheel meshes ay pinion 34 on Ithe upper end'ofa vertically disposed 'shaft 35. This shaft extends down into a gearhousing 36 and is provided near its lower end with a bevel gear 37disposed in mesh with a similar pinion gear 38 on a horizontal shaft 39,which horizontal shaft is shown -inFigures 2 and 18. The horizontalshaft extends through the hollow pedestal 24, suitable bearings beingprovided therefor; and at an intermediate portion of the shaft 39 iS aworm 40 disposed in mesh with a worm wheel 41 fixed upon a verticalcentral shaft 42. The lower end of theshaft 42 is carried in the spiderarms 43,

shown in Figure 2, at the base of the hollow pedestal. The shaft 39 isdriven by a sultable source of power (not shown). The shafe 39 will,therefore, rotate the spider construction which carries all of themolds,

and it also serves to rotate the shaft 42 byv .which certain furtheroperations in connection with the molding are carried out.

Referring to Figures 2 `and 7, the outer ends -of the spider arms arearranged to carry the mold transferring apparatus, and in the outerbearing vportion 30 of each spider arm is placed a cylinder 44 having aplug 45 in its lower end through which is slidably fitted a plunger rod46carrying the plunger 47, which is fitted to reciprocate in thecompressed air cylinder 48 secured beneath the flange l49 of saidplug45.` The air connections to the cylinder 48 are shown at 50 and 51.

The upper end of the plunger rod 46 is pivotally coupled to a link 52and this link is in turn pivotally coupled to a gear'segment`53 rotatingabout a center 54 on an appropriate fixed part of the machine. The' gearsegment 53 meshes with al pinion 55 journaled above it upon a shaft 56.This pinion, or the shaft 56, carries an offset arm 57 to which the neckmold 58 is att-ached. As shown in Figure 7, by dotted lines, the arln 57and neck mold 58 may be swung over at substantially 1800. The neck moldand arm` 57 occupy initially the inner position, shown in full line-s;lthat is, a position upon the inner circle of the machine.l In thisposition the blank, indicated at '59 in Figure 7 is formed within theblank mold composed .of the sections 60 and 61 carried by the clamp jaws'62 and 63. These clamp jaws are shown in Figures 14 to 17 inclusive andwill be referred to later.

As shown in Figure 2, the blank mold is initially adapted to receive thecharge of glass from an overhead source of supply or reservoir indicatedat 64 by control of a valve plunger 65. A gob of glass is indicated asfalling from the source of supply to the blank mold, it being receivedin the blank mold through the funnel 66 carried by the arm 67.

The glass is' received in the blanl: mold to the quantity indicated inFigure 8, this glass body being indicated at 68. The neck mold 58 isshown as having received through its orifice the plunger 83 having theupper rounded head to form an initial cavity in the body of glass and toguide this body of glass, into the Circular cavity of the neck mold 58.The plunger head 59 is carried upon the apparatus, shown in -Figure 7andthis apparatus is intended to be withdrawn downwardly to permit theblowing apparatus 69, shown in Figure 9 to be applied beneath the blankmold. By this blowing apparatus 69 the blank is blown into shape, asshown in substituted therefor.

complishing these results is shown in Fig-l direction The stream Figure9, the funnel 66 being previously .withdrawn and the bottom mold plate70 The apparatus for ac# ure 12.

After the operations shown in Figures 8 and 9, the sections 60and 61 ofthe blank mold are separated, these sections being pivoted together andadapted to open out, as shown'in Figure 1. This permits the neck moldand the blank or dummy to be swung. over. as indicated in dotted linesin Figure 7. When swung to t e final position on the outer circle, thedummy will fit into the bot- ,tom mold plate 71 carried upon the arm 72.

The dummy will also be in position to receive thereabout thesemieircular mold sections 73 and 74 of the finishing mold, which lmoldsections are carried by the -clamp jaws 75 and 76'illustratedin Figures14 to 17, to which reference will be made later. The

finishing operations areV indicated in Fig,-r

ures 19 and 11. Figure 1l showing .the

blowing apparatus 77 applied to 'the neck mold 58 for the purpose offinally blowing the glass bottle 7 8 to shape.

In Figure 11 the blowing apparatus is shown as comprisingv a pipe 79through which the air' is delivered in a downward of airmeeting theabutment 80 will 'be diverted to the peripheral edge of this abutmentwhere passages are provided to admit the air around the edge and beneaththe abutment to the cross passages-81 by which the air finally issuesthrough the axial passage 82 and into the neck of the mold. This insuresthe gentle vfeeding of the blowing air.

Returningto Figure 7, the plunger head 83 is screw threaded or otherwiseremovably coupled to the plunger rod 84 movable through the operation-ofthe plunger 85 which reciprocates in the cylinder 86. rlhese cylinders86 are carried upon spider arms k26, such spider arms being providedwith openings 87 to .admit air .into fthe bases of the cylinders 86beneath the plungers 85.

In Figure 7 is also shown the cam 88 carried by the arm89 lfrom the gearbox 36. This cam encounters the roller 90 upon the lowerl end of theplunger valve 91, which is kept down to its seat normally by the spring92, but which opens on raising of the valve to permit air to enterthrough the port 93 pass the valve and issue through the port 94.

Referring more particularly to Figures 14 to 17 inclusive,"the .clampdevices are shown for carrying the mold sections, but

blank mold are at a higherV elevation than the clamps 75 and 76 for thefinishing mold as will be obvious from Figures 15 and 16 and from thepositions which the two molds comparatively occupy, as shown in Figure2.`

These clamps are intended to be alternately opened and closed and theycan, therefore,

with economy in the manufacture and with simplicity in the operation bemade in one piece. That is, one of the blank mold clamps 63 is made inone piece with one of the finishing mold clamps 76, while the otherclamps 62 and 75 are made in another piece.

The unit 63, 76 is made with the spaced bearing rings 95 and 96, whilesimilar bearing rings 97 and 98 are made upon the other unit... Theserings are at the angle portions between the clamp jaws and such ringsare intended to be nested together, so as to inter fit, as indicated inFigure 17, and to all receive the c v'linder 44, or some otherappropriate turning post about which the clamp units may be swung. SeeFigure 1, for the various positions of these clamp units.' The clampunits are further provided y with'the' perforated ears 99 and 100 forthe purpose of receiving the curved arms 101 and 102, shown in Figures 1and 14. These curved arms are pivotedat`103 andI 104 and they areprovided with the straight tail pieces 105 and 106. Links 107 and 108are pivoted to the tail pieces 105 and 106 and these links convergeinwardly and are pivoted as indicated at'109 through a block 110 whichblock is slidable in the guide casing 111. The block is provided with aroller 112. The b'lock 110 is provided with one or more lateralindentations 114 into which are urged by springs 115 the blocks 116. y

The roller 112, as shown in Figures 1 and 2, bears against the cam iange117 on the cam plate 118 extending about the upper portion of the hollowpedestal. The cam plate 118 is stationary and it is further providedwith two other cam plates 119 and 120 which arel .secured to the camplate 118 and extend.

bevond the cam flange 117 and above the same. These cams 119 and 120 areshown as ot' sector shape in Figure 1 and they only extend around aportion of the circumference of the machine corresponding to certainstages of the operations. The cams 119 and 120 are disposed in positionto be engaged bv a roller at the'pivot point 109 between um links 107 mi108.

1n Figures 5 and 6 is shown the guide plate having a ring 121 extendingabout the hollow pedestal` as shown in Figure 2. The ring 121 isprovided with the V-shaped arms 122 and 123 between which are providedthe radial slots 124. In these slots the side extensions 125 of theslide casings are fitted for radial movement, shoulders or seats 126being provided in the slots 124 to receive the same. The parts 125 areshown in Figure 14 and there seating upon the shoulders is shown inFigure 1.

Reverting to Figure 7, thecylinder 86 is provided with an outstandingannular ribl 130 upon which slides a casing 131 having a `ing the easingnormally down and the ports 132 and 133 out of registry. Above the rib130 and in the cylinder 86 is a port 138. Air is adapted to beintroduced through this port, such air being received through the port139 in the outer casing 131.

Referring aga-in to Figure 2, at the upper end of the central shaft 42is a head 140 rotating with the shaft and having av notched flange 141extending from a low point thereon. yA roller 142 is adaptedto cooperatewith these notches. This ro'ller 142 is earried by a. plunger 143, whichslides inf'a cylin-y der 144 carried by the arm 145. In the cylinder isa plunger 146 for urging the roller into the notches. A coil spring 147is engaged behind the plunger 146.

Loosely mounted over the rotating head 140 is a sleeve 148 by which thearm 145 is carried.. This sleeve also carries at the opposite side, asshown 'in Figure 12,.a support 149 for the arm l67. Such arm 67 carriesthe funnel 66 as previously described and it also carries above thefunnel the guide way 150 for the slide 151 employed to close the funneland having an apertured pin 152, this pin being used as a bearing forthe arm 153. When the slide is in a closed state, compressed air isadmitted through the hole in the pin 152 and into the funnel, therebycompressing theglass in the blank mold. The slide 151 is also shown inFigure 8. The slide is operated back and forth by a lever 153 fulcrumedat 154 upon an appropriate part and being actuated by a plunger 155 in acylinder 156. Before the plunger 83 is removed, the slide 151 closesover the funneland compressed air is admitted through the pin 152 onlthe slide into the blank mold, compressing the glass in saidA blankrnold. At 157 is shown a cylinder having a piston 158 therein coupled toa piston rod 159 pivoted to an arm 160 upon the cam plate 118.

In the operation of the machine, the initial stage is shown at the rightin Figure 2, where the blank mold is arranged beneath the souce ofsupply with the funnel 66 in place thereabove and with the slide 151 inthe position shown in Figure 12. The supply of glass is then permittedto drop into the blank mold up to substantially the level shown inFigure 8. The plunger 83, vshown in Figure 8, is then removed byadmitting air to the apparatus, shown in Figure 7,

through the orts 139 and 138, thus depressing the p unger 85 by whichthe plunger ead 83 is carried. The air admitted through' these portsalso acts against the rigid rib 1130 forcing the slidable casing 131upwardly to cause registration of the ports 132 and 133 through whichair is admitted to blow the blank into the condition shown in Figures 7and 9,. It will be understood that the ports 132 and 139 are connectedto an appropriate source of compressed air supply.

Just prior to the blowing operation the funnel 66 is shifted away byoperation of the piston 158 and cylinder 157, shownin Figure 12. Asvshown in this same Figure 12, the cylinder 157 is coupled tothe arm 67which carries the funnel 66.

The machine is continuouslyrotated, the stages of operation being notedapproximately by the legends in Fig. 1.' In the course of this movement,the mold sections 60 and 61 of the blank mold are opened out,

for instance, as'shown in Figure 1. This leaves the dummy 59 supportedinthe neck mold 58. Subsequently the neck. mold .is swung over, as shownin dottedI lmes 1n Figure 7, air for this purposebeing admitted beneaththe piston 46. This will bring the dummy to a position on the outercircle andl following its arrival to this position, the finishing moldsections 73 and 74 are brought together upon the dummy. This swinging ofthe mold sections is accomplished by the cams acting upon the rollers109 and 112.

The air blowing apparatus 77 is thereupon applied to the neck mold andthe' finished bottle blown. The bottle is subsequently removed byseparation of the finishing mold sections.

It will be appreciatedthat due to the -hollow colulnn and hollow armconstruction,

cooling air may be circulated to all parts of the machine. It will alsobe appreciated that the design of themachine is simple in construction,light in weight and condensed so as to occupy a minimum of iioor .spacewith a minimum amount of parts, thereby reducing friction to a minimum.

' The machine, because of these features, is able to operate lat higherspeeds than present types of similar machines. The machine will alsohave a wide working range capable of making a bottle of 11/2 high to 15in height on the same machine.

'The head 140, Fig.l2, is affixed to the shaft 42, and is continuouslyrotating `therewith. The arm 67 works freely around head 140, only whenthe roller 142 registers in one of the notches in disc 141. vvVhen theroller 142 registers into one of these notches, the arm 67 rotates untilthe head, or for- 159. This small valve directs the air into weaves 142from the notches inV disc 141, and at the same time admitting air intokthe rear of cylinder 157, this air bearing against the plunger 158forces the arm 67 to its original position, under the flow of glass.This intermittent stroke of arm 67 is adjustable by moving the smallvalve on plunger rod 159, in either direction.

The function of roller 142, which snaps in the notches in iange 141, isto keep the arm' 67, the funnel 66, and the baiiie plate 70, which aremountedon arm-67, in alignment with the blank molds underneath so -asthe different operations of forming the dummy in said blanks may beperformed whilst the blank molds and arm 67, together with the partsmounted on` said arm, are revolving with the machine. After theoperationat Fig. 8 and Fig. 9 are performed, the roller is released fromthe notch, and arm 67 is brought to the preceding blank, that is whenthe roller snaps into the preceding notch.

The valve 91 shown at right-hand corner perfect i of Fig. 7 is used todirect-the air into the blow head 77, which tends to blow the bottleinto shape, shown more clearly in Fig. 11.

It is obvious that various changes and modilicationsmay be made in thedetails of construction and design of the above specifically describedembodiment of this invention without departing from the spirit thereof,such changes and modifications being restricted only by the scope of thefollow ing claims.
